The Royal Oak Chronograph was a latecomer to this celebrated line and has remained remarkably consistent throughout its two-decade life. All share the same movement and a single lineage passes from the original Ref. 25860 to the subtly-redesigned Ref. 26300, the up-sized Ref. 26320, and the new Ref. 26331. It was only this year that a second model, the 38 mm Ref. 26315, was added. Yet on closer examination, a world of differences emerges, from the City of Sails to the Leo Messi, to the new 41 mm dial. Through it all, the Royal Oak Chronograph remains one of the classiest and most comfortable watches available.

Given the clever retrograde chronograph movement, the Gran’Sport Chronograph is the pick of the Gran’Sport lineup today. It’s really too bad that gorgeous Reverso Chronographe Rétrograde is out of the price range for most people.

Despite the sketchy history of the design, Movado’s “Museum Watch” remains an icon of horology. It’s one of the very few watches that is instantly recognizable even to the uninitiated, and thus belongs in any serious collector’s watch box, if not on their wrist.

I’ve got a thing for classic dress watches in general and Patek Philippe Calatravas in particular, so I get excited when I see a real classic come up for auction. Such is the case with this Ref. 5015 Moon Phase Power Reserve: It’s not technically a Calatrava, but it features all the best elements of that line. Starting at just €7,000, who’s bidding?

Apple will today detail their Watch, ending years of speculation. But Jony Ive and Marc Newsome are not the first Apple designers to create a watch, and the first one out of the gate was truly revolutionary. Pushed by legendary designer Hartmut Esslinger of FROG Design, the Junghans Mega 1 was the first miniaturized atomic clock receiver and sported a distinctive ceramic case.

Here is a Lange Datograph Flyback, model 453.135. This was the very first Datograph model, cased in platinum, and featuring the then-new Calibre L951.1. The black Roman numeral dial catches the eye, but one should note the bracelet which suggests that this is one of the earliest Datographs produced.

At this risk of this becoming “Grail Seiko” rather than “Grail Watch”, please allow me to present two wonderful and very rare watches for your consideration. Both are gaudy gold watches, both are relatively modern, and both are probably overpriced except in the eyes of a true Seiko fanatic. But one is an homage to Seiko tradition while the other was the first attempt by the company to take on the Swiss!

How would you like to own an extremely rare and interestingly complicated watch from a legend of independent Haute Horology? This worn but interesting world timer watch was constructed by Svend Andersen in 1992 to commemorate the 500th anniversary of Christopher Columbus’ journey to the new world. And it’s definitely worth the starting bid of € 4,000.

Exotic materials are fairly common in modern watches, with most manufacturers augmenting their lineup of stainless steel and gold cases with titanium, platinum, and ceramic today. But what about really-unusual materials like rhodium and even tantalum? Yes! Many manufacturers have used these materials, though they’re certainly not common…
